2 'SHEETS- SAHT'Z gresses, one of the essentials of which is that the key board must not project in a plane above the basket, and that for the greatest possible ,convenience of inspection ot' the writing the basket shall be in depth as shallow as `is consistent with the length of type bars necessary for their practical operation.

The prime object of my invention, broadly stated, is, therefore, a book typewriting machine having the lowest possible key board, shallow depth of basket and lightness oi' action, and sible, plainly and conveniently visible to the operator as it progresses in the absence of A further object of my invention is to rein which the writing is acces,

levers, the means by which the shiftable.

tain in a visible writing book typewritingmachine the old and well known circular arrangement of type bars, the location and connection of the key levers with the type bars forming the liront half oi their coniplete circle, and to operate from keys in lower planes than those first above inentioned the key bars of the rear haltl of the basket by means unobstructin'g the opening through the basket, whereby the writing of the machine as it progresses may be clearly visible to the operator at any time without lifting the type carriage.

Most speciiically stated, the object of my invention is to make it possible `and practical to loca te and arrange all of the key levers outside of and laterally beyond the basket formed by a circular arrangement of the type bars ot a book typewriting machine,

and to so connect said levers with the type' bars trom the rear haii" of said circle that a- 'type bars ot the 'front halt ot' their circle therein, or the key levers for actuating said. bars.

lVith these -ends in view, my invention linde embodiment in certain features et novelty in the construction,` combination a nd arrangement ot' parts by which 'the said objects and certain other objects are hereinafter attained, all as fully described with reference to the accompanying drawings, and more particularly. pointed out in the claims.

ln said drawings x.lligure l. illustrates a top plan view of a visible book typewriting machine in which type heads are actuated and maintained in their adjustment, and the means for shitting the ribbon when uncovering the writing for inspection.

Similar characters of reference indicate the same parts in the several figures of the drawings.

As the means for supporting and the meeltanism for propelling the type carriage forms no .part of my present invention, l have shown (see Fig. 1) only the side bars 4--4 of the open frame, the end bars 5 and 6 of the slidable frame mounted thereon, the shat't 7 upon which the type carriage is swung, the rack bar 8 embedded in said shaft for engagement with the pinion 9 ol the propelling mechanism 10, and of the con struction and arrangement heretofore commonly used for many years in the Elliott & Hatch book typewriter, and in which the carriage is sustained by means of pulleys 11, 1l on studs 12 projected from the legs 1.3 from an arch plate resting from the bed plate- 1l of the type carriage, which also supports grooved wheels 15, 15 and 16, lli embracing the opposite sides of the shaft 7 in the usual manner and for the purposes of steadying the type carriage in its travel along its supporting shaft 7 the arch plate and bed plate being, as usually, in the form of an angular casting secured to the usual bottom ring 17 of the basket-like structure 18, the sides of which are closed by the type bars in circular arrangement.

To the ring 17, toward the front side thereof, are secured the outwardly projecting brackets 19, supporting, (see Figs. ,l and 3) by means of screws 20, an upper plate Q1 and a lower plate 22 connected together at their ends, as indicated at4 and forming, as a whole, an open oval-like plate, to the outer end of which are secured lifting levers 24. 24 respectively provided with linger pieces and 2G as a convenient' means for swinging it on its supporting shaft 7 when occasion may require. l.

l u a plane above the base ring 17 and sup ported by one or more suitable rods 27 is a ring 28, within which and the ring 17 are arranged, in the rear half of their circle. type bars 29, and in the front halfoic their circle type bars 3U, to the usual total numrespective key ievers, and in enen f i f levers and theif connections.;

t this understanding of the instrucn machines of' the eonstrnction o" toe hlhott Hatch typewriter, and as may that ati, of the hey lovers for the type tion, arrangement and operation of the longest shafts with the rearinost type bars of the basket, it is so obvious that other than in decreasing length of shaft connections as the type bars approach, their outermost position in the basket is and must be precisely the same, save that the shafts are gradually decreased in length.

In every instance, however, it will he seen that 'the force for actuating the shafts and imparted by them to the type bars, is at substantially a right angle to the length oi said shafts, with the result that the force is transmitted from the keys to the type bars in the b est possible direction for its utilisation, and also for promoting ease of action of the several mechanical parts, and lightness of touch as applied to the keys, while at the saine time there is no obstruction in the opening through the basketto the writing of the type striking the pages of a. book as they do in every instance axially of the circle formed by the keys.

For shifting the ribbon away from the Writing for inspecting the sa me, may eniploy a ribbon shifter 78 grasping the ribbon -for permitting it to freely pass therethrough and actuating this ribbon shifter by a rod 79, provided with an upwardly bent portion 80 having a sliding bearing on a bar Si and actuated by a duplex crank arm 82, tulcrumed at 83 in a stud 84C, operated by the spacing bar mechanism of the machine as commonly constructed, consisting Aof bent side bars 85 and 86 fulcrumed at the rear of the machine and engaged to each and the several key levers thereof.

So far as the broad idea oic my invention is concerned, any other construction of i-ibbon shifter, adapted for the purposes above described, may be used, and this is also equally true of the ribbon spools S7 and SS for the ribbon 89 and the actuating devices 90 and 91 therefor, and in short l propose to use in the construction of the machine of my present invention substantially the saine feed, ribbon and spacing bar mechanism as has been used for many years in the `Elliott t Hatch machine upon the market, and for the purposes of the visibility' of the writing of which without lifting thc type carriage my present invention is especially designed and adapted.

In other words. the only substantial changes required to convert the old and well known Elliott Xs lil'atch book typewriter into a successful and practical visible book typewriting machine are accomplished by lowering its upper two banks of key levers, below the remaining` key levers, substituting therefor the bent levers before described :for operating the type bars in the rear half of the basket -and connecting them with the shafts in stepped` plates mounted respectively upon the lower and upper base portion ai'. the ifi-ont and back of (he machine with the stepped shafts therein connected, as before described` with the type bars.

The construction and arrangement of parts by which the old non-visible Elliott d: Hatch book typewriter is made a visible writing machine is so simple and cheap that ii" may be adapted thereto with success at a cost substantially less than ten per cent. of that oi the original machine.

Having described my invention, what I claim desire to secure by Letters Patent is 1. A. book typcwriting machine carriage comprising' in combination type bars form ing a complete circle of open basket-like arrangement, key levers, and rock shafts extending at a right angle to and connecting said levers, type bars at and for the rear half of the basket, and means for operatively connecting the type bars with said shafts and key levers, substantially as described.

A book typewriting machine carriage comprising in combination type bars arranged to form a complete circle of open basket-like arrangement, straight line key levers for actuating said type bars, 'rock shafts of differing lengths located above the bottom of the basket, operatively connected with said key levers and extending at a right angle to the length of the key levers, substantially described.

A book typewriting machine carriage comprising in combination type bars in circular open `basket-like arrangement, rock shafts in a plane just above the upper ends of the type bars adjacent the rear end of the carriage, crank arm connections between said shafts and the type bars, a corresponding series of shafts in a plane below the upper ends of said type bars, rod connections between the outer ends of the opposingr upper and lower shafts, key levers connected with the inner ends of the lower shafts, and a single shaft constituting a iulcruni coinmon to all of said key levers, substantially as described A book typewriting machine carriage comprising in combination type barsforming a complete circle of open basket-like arrangement, key levers for actuating said type bars in the rear half of their circle, the bank of keys for said bars being in a plane be .fw 'the keys for all other type bars, and Connecting rock shafts differing in length but of the same length for corresponding type bars at opposite sides of the basket, substantially as described.
